  简介:
N Fermions with k−body infinite-range interactions, originally introduced in the
context of quantum chaos, and recently re-labelled Sachdev-Ye-Kitaev (SYK) models,
are attracting a great deal of attention in both high energy and condensed matter
phyics. In the first part of the talk I explain the reasons for this interest. Then, I present
some of my recent contributions to this problem, including a detailed analysis of
thermodynamic and long time dynamical properties, that strongly suggest that the
the SYK model, and its supersymmetric extensions, are toy models for holography and
that random matrix correlations are a universal feature of both quantum black holes
and strongly-coupled metals. Finally, I discuss the robustness of these features by
studying deformations of the SYK model which undergo chaotic-integrable and metalinsulator
transitions.
